  Call your healthcare provider right away if you have symptoms of an infection such as: fever, sweats, chills, cough or flu-like symptoms, muscle aches, or warm, red, or painful areas on your skin.

Do not take ENVARSUS XR if you: are allergic to tacrolimus or any of the ingredients in ENVARSUS XR.

Before you take ENVARSUS XR, tell your healthcare provider about all your medical conditions, including if you: plan to receive any live vaccines, have or have had liver, kidney or heart problems, are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed.

If you are able to become pregnant, you should use effective birth control before and during treatment with ENVARSUS XR.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, natural, herbal or nutritional supplements. ENVARSUS XR may affect the way other medicines work, and other medicines may affect how ENVARSUS XR works and cause serious side effects.

Especially tell your healthcare provider if you take a seizure (anticonvulsant) medicine, medicines to treat infections (antibacterials, antivirals, or antifungals), or other medicines that prevent rejection of a transplanted organ. Do not start or stop a medicine without telling your healthcare provider first.

While taking ENVARSUS XR, avoid live vaccines, exposure to sunlight and UV light such as tanning machines, eating grapefruit or drinking grapefruit juice, and alcohol.

ENVARSUS XR may cause serious side effects, including:

• Problems from medication errors such as graft rejection and other serious reactions. People who take ENVARSUS XR have sometimes been given the wrong medicine because some medicines have the same ingredient (tacrolimus) as ENVARSUS XR. Check your ENVARSUS XR when you get a new prescription to make sure you have received the right medicine.
• High blood sugar (diabetes). Call your healthcare provider right away if you have frequent urination, confusion, fruity smell on your breath, increased thirst or hunger, drowsiness, nausea, vomiting or stomach pain, blurred vision, or loss of appetite.

• Blood clotting problems. Tell your healthcare provider right away if you have fever and bruising under the skin that may appear as red dots, with or without unexplained tiredness, confusion, yellowing of the skin or eyes, decreased urination. When taken with sirolimus or everolimus, or when you develop certain infections, the risk of developing these symptoms may increase.
